Added mask to SSIM function call

[FelixSteinbauer]

I think the mask should also be provided to the SSIM function call. As the mask variable is always present/valid (either a proper mask if provided by the user or all-ones, see variable initialisation), it should be fine to simply add the mask as parameter to the call.

In my opinion, structural_similarity_index() should work fine with this additional parameter and nothing should break. However, I did not test the suggested code change.

This really is just a very minor change so please don't be mad at me for not following the standard PR procedure UwU

Proposed Changes

• Set "mask" as optional parameter to structural_similarity_index() for the "synthesis" metric computation case.

No need. Once it gets recorded in the system, it will auto-propagate. 😄

As soon as I find a printer and scanner, the cla-check will also pass 👍 (probably tomorrow)
